Biological enzyme purifying agent for treating black-odor river and preparation method thereof

Abstract

The invention discloses a biological enzyme purifying agent for treating black-odor river The biological enzyme purifying agent for treating black-odor river comprises the following components in parts by weight: 20-50 parts of biological enzyme, 10-15 parts of rhodococcus erythropolis sludge flocculant, 10-18 parts of chitosan quaternary salt, 10-15 parts of grape seed extract, 5-15 parts of sweet potato extract and 10-15 parts of polyaluminium chloride and 8-12 parts of polygalanthamine. Under the combined action of a plurality of components, the water purification effect of the water body is remarkable, the quality of the water body can be obviously improved, the dissolved oxygen content in the water can be improved, the growth of the harmful bacteria is inhibited, the suspended mattersand harmful algae in the water are removed, the content of the nitrogen and the nitrate nitrogen in the water body is reduced, the water body is clarified, the odor is eliminated, the degradation ofthe pollutants is promoted, and the benign development of the water is promoted. The raw material resource used is rich, the preparation process flow of the water purifying agent is simple, the production period is short, the operation is simple, the production cost is low, and the water purifying agent is suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of ecological environment, in particular to a biological enzyme purifier for treating black and odorous rivers and a preparation method thereof. Background technique [0002] Black and odorous water is an extreme manifestation of organic pollution in water. It is caused by the lack of oxygen in the water and the corruption of organic matter. When a large amount of organic pollutants enter the water, under the purification of aerobic microorganisms, a large amount of oxygen in the water is consumed. Transform the water body into an anoxic state, resulting in a large number of anaerobic bacteria. [0003] Due to the problems left over from history, most urban rivers are carrying sewage, and a large number of pollution sources such as domestic sewage, domestic garbage, and industrial wastewater enter the river, resulting in the phenomenon of black and smelly rivers, which seriously affects the normal life of su...

Problems solved by technology

[0005] In the prior art, there are biological enzymes used to purify water, but most of them are simple combinations of microorganisms and biological enzymes, and the purification effect is unstable and the effect is average.
